Title: Driving method for signal selector
IPC: H03K17/62
Filed: 1992-03-11
Abstract: PURPOSE:To preclude the possibility of occurrence of leak current noise or capacitive coupling current noise due to a reverse bias voltage by driving a light emitting diode so that its earth side is not turned off when its power supply side is turned on. CONSTITUTION:Drive signals GR1-GRn of a signal selector in which lots of semiconductor relay switches are formed as a matrix are inputted to bases of drive transistors (TRs)Qc1-Qcn of the earth side of light emitting diodeRL1-RLk. Moreover, drive signals ChS1-ChSm are inputted to bases of drive TRsQa1-Qcm at the power supply side of the light emitting diodeRL. Then two drive TRs or over at the earth side or the power supply side are driven so as not to be simultaneously turned on. Moreover, the TRs are driven when those at the earth side are already turned on when those at the power supply side are turned on. Thus, a potential at a connecting point P of the cathode of the light emitting diodeRL is always kept close to zero even when the anode side is changed over.

IPC: B01D63/02
Filed: 1994-02-25
Abstract: PURPOSE:To effectively remove an accumulated substance or fine particles in pores within a short time by a reduced amount of water. CONSTITUTION:Raw water containing a suspended substance, for example, org. or inorg. matter is treated by passing through a hollow yarn module while transmitted water is guided to a washing water tank 11 and, when the inner walls of hollow yarns are clogged, a chlorine type oxidizing agent is added to the treated water guided from the washing water tank 11 to backwash the hollow yarn module and, in order to further effectively remove the deposit bonded to the inner wall of the hollow yarn module, air is blown in one port, for example, the concentrate outlet 6 of the hollow yarn module to discharge the deposit from a raw water injection port 5. The blowing-in pressure and amt. of air is desirably set to a degree generating turblent flow in the module. Since the washing water exuding to the interiors of hollow yarns is accelerated by the air flow in the hollow yarns to remove the deposit on the inner walls of the hollow yarns, large washing effect is obtained.

Abstract: PURPOSE:To prevent the occurrence of traveling malfunction of a tape and flawing of a head by rotating a rotary head drum in a prescribed direction at a prescribed speed after stopping the tape with a tape stopping mechanism under the stopping state of a tape driving mechanism. CONSTITUTION:At the time of shifting from a tape loading completion state to a tape traveling operation state, the rotary head drum 2 is rotated for a while, so as to perform various tape traveling operations. When this standby state is inputted, confirmation is made by a timer as to whether the device is left as it is under the tape loading completion state for more than a prescribed time. Then, when the device is left more than the prescribed time, a pinch roller 16 is operated to pressingly hold the magnetic tape 6 with a capstan 47. Under this state, a drum motor is rotated at a prescribed revolving speed in the direction opposite to the capstan and the pinch roller, and when an FG output of this motor is abnormal, it is decided that the tape sticking to the drum 2 should be taking place, so that the rotation of the motor is stopped, and an alarm is lit to tell the abnormality.

Abstract: PURPOSE:To supply only a conforming article to the treating stage after the coating stage and to efficiently reduce the working cost and material cost by detecting a film thickness in the radial direction as well as in the peripheral direction during the rotational coating. CONSTITUTION:A body 1 to be coated is placed on a chuck 4 and fixed by vacuum suction. A coating soln. 2 is dripped from a nozzle 3. The chuck 4 is rotated at high speed for a specified time by a motor 5 to expand the coating soln. 2 by centrifugal force, and the film of the coating soln. 2 is formed. When the body 1 is irradiated by the laser beams from He-Ne lasers 50 and 51 during coating, the beams are reflected by the interface between the body 1 and the film of the coating soln. 2 and by the interface between the film of the coating soln. 2 and the atmosphere, and the beams interfere with each other.
